Rotate Jacks In Their Mounts To Gain Trailer Clearance?

Removing the powerhead is real simple. I had one motor go bad several years ago (replaced under warranty). IIRC there is nothing in there to loose or fall out when lifting the powerhead.

However I don't positively remember whether or not it is indexed, I don't think it is though. IIRC the two screws showing in your photo are not the ones to remove/rotate the powerhead. I think the one screw showing above the two is in the right area. There obviously will be more than one.
